Queen In Hyun's Man
To The Beautiful You
Panda and the Hedgehog
I Need Romance Season 2
Rich Man, Poor Woman
A Gentleman's Dignity
Those are all the ones I've watched from this year. I haven't watched Queen In Hyun's Man though, but I've heard its a great romance drama. However I would recommend watching Reply 1997, I Need Romance 2, A Gentleman's Dignity and Rich Man, Poor Woman first.
